First the bad news, I road the Thunderbird and was disappointed. If I was in the market for a big cruiser, it would still be a Warrior. The T-Bird was very comfy but the brakes were meh and it's looks don't sing.
On the AMAZING side, I rode a street triple R with the arrow slip ons. Man, Pete's Cycle got a flat orange Street Triple R about 2 months after I bought my Tiger. If it had been there, that's what I'd be riding.
So light and so THIN. Man. Perfect riding position, dead natural. The thing absolutely sings with those Arrow pipes. I WANT ONE!
Seriously tempted to trade the Tiger, but I'd lose to much in the extras.
Also there were several bonnies, a thruxton and a scrambler with the arrow pipes. Those things sound SICK. I've got to say, that scrambler sounds better than my speedy with specialty spares.
